The BBFC is a not-for-profit organisation funded by the film and TV industries.

A spokeswoman for the BBFC said sex works are currently examined by teams of two and a final decision on the proposed changes had not been taken.

She told the Guardian: "The BBFC is currently consulting staff about a proposal that sex works should also be examined by examiners viewing alone, but only on the basis that an appropriate policy is in place for having works which are particularly problematic or unpleasant viewed by teams. Difficult or unpleasant issues or material are not confined to sex works."
